2. Let the price elasticity of demand for a soft drink be – 2. In the year 2020, the per capita consumption of soft drinks was about 500 cans per person, and the average price was $1.00 per can. If we suppose that demand for the soft drink is linear, 
, where a and b are constants, 
is quantity demanded and P is price, an estimate of the demand equation could be:
(A) 
= 100 – 2P
(B) 
= 1500 – 2P
(C) 
= 1500 – 1000P
(D) 
= 1000 – 1500P
